ViewCell blows up every time

On WinPhone, If I set any content inside the below ViewCell (see example Button), I get the following exception:

Message = "MeasureOverride of element 'Xamarin.Forms.Platform.WinPhone.ViewToRendererConverter+WrapperControl' should not return PositiveInfinity or NaN as its DesiredSize."

I'm not sure when this started - both XF 1.4.1 and 1.4.2 are doing it today.
